Twilight (Star Trek: Enterprise)

"Twilight" is the eighth episode of the third season of the American science fiction television series Star Trek: Enterprise, originally broadcast on November 5, 2003. It was the sixtieth episode of the series overall. It was written by co-producer Michael Sussman, and directed by former Star Trek: Voyager actor Robert Duncan McNeill.

Set in the 22nd century, the series follows the adventures of the first Starfleet starship Enterprise, registration NX-01. In this episode, following an accident, Captain Jonathan Archer's (Scott Bakula) long term memory is affected and he is relieved of duty. The crew of the Enterprise subsequently fail to stop the Xindi attack on Earth resulting in the remnants of the human race resettling another planet. Dr Phlox (John Billingsley) finds a way of curing Archer in the past, in the hope that it would undo everything since the Captain was originally injured.

The episode and script was praised by Bakula during the shoot, which required the actors and sets to be aged to appear older in later time frames. Production was suspended for a day following the death (at home) of first assistant director Jerry Fleck, who was in pre-production on the next planned episode, "North Star", which subsequently resulted in crew changes on "Twilight". References in the episode were made to locations previously mentioned in the Star Trek: The Original Series episode "Space Seed" and the film Star Trek II: The Wrath of Khan. On first broadcast, "Twilight" was watched by 3.88 million viewers, more than the following episode. The critical response was positive.
